Gain Up to 35HP. If you have a blown or modified setup in your New Edge Mustang, upgrading to a Granatelli Coil-on-Plug kit will deliver the spark your Pony needs to get the most from your mods. Your weak OEM coils don't deliver a strong enough spark to your plugs to ensure you're getting the most power possible from your engine, especially once you've added high performance parts. This kit adds up to 15HP on naturally aspirated Mustangs and an impressive 35HP on turbo or supercharger setups.
Up to 400% More Voltage. Your stock coils deliver 20,000 volts, versus the GMS coils which are rated at 60,000 volts. And this kit features a no-resistance connector cable design so all of that voltage is being delivered where it counts.
Complete Kit. This complete kit includes all hardware necessary for installation including the 8 coil packs, connector cables, and stainless snap lock plug connectors.
Easy Installation. Upgrading your coils is easy with this kit, which is OBD-II safe and a direct replacement for your OEM setup. You'll enjoy more power, improved throttle response, and even better fuel economy with an hour or less install time using basic hand tools from this GMS Coil Plug Kit.
Application. The Granatelli Coil-on-plug upgrade kit is designed for 1999-2004 SVT Cobra & MACH1 Mustangs.
